Specification of Letters Patent.

Patented Dec. 8, 1914.

Application filed May 6, 1914. Serial No. 836,657.

To all whom 'it may concern Be it known that I, Rona'r EMnnsoN Brown, a citizen of the United States, and a resident of Olean, in the county of Cattaraugus and State of New York, have 1nrented a new and Improved Safety-Raccr- Blade Holder, of which the following 1s a full, clear, and exact description.

My invention relates to safety razor blade holders-that is, to devices used for holding a safet razor blade during the operation of honlng or strapping the blade.

.Dls is well understood in this art, safety razor blades, because of their form and sharpness, are exceedingly7 diiiicult to handle without danger of an accident, and the diiiiculty of handling the blade is increased' because of the fact that the honing and strapping of the blade is'done quickly.

i seek to produce a safety razor blade holder in which the razor blade can be quickly and positively clamped, and when onse in position is not easil disturbed. lider-cover, I seek to' roduce a evice of this phare-reiter in which b ades of all sty1esthat is to say,"with or without backs, and having reasonable width or any thickness likely to` be employed, ma be held. I further to produce a sa ety razor blade holder in which the blade can be secured without undue precaution being taken and without requiring greater care than the average person is li e y to use. I further seek to produce a blade holder which, when used for purposes of honing or strappin the blade,

will necessarily present the bla e at a suitable angle to the strap or hone.v In addition, I seek to accomphsh other results looking toward improving the general eiiciency or" devices of t is characte M I Reference ais made to the accompanying drawings forming part of this specification and in which like'letters indicate like parte.

Figure 1 is a view, partly in plan and Apartly in rg7section, showing my improved safety razor blade holder; Fig. 2 is aside elevation of the same; Fig. 3 is a section on the line 8-3 of Fig. 2, looking in the direction. of the arrow; Fig. 4 is a fragmentary view, partly in bottom plan and partly in section, showing the device with the movable parteA occupying certain predetermined positions; Fig. 5 is a view somewhat similar to Fig. 4 but showing the movable parts as occupying different positions from those indicated in said figure; Fig. 6 is a detail view, showin in side elevation a portion of one of the side bars; Fig. 7 is a perspective view showlng a protector used for encircling the blade while carried in the holder but not in use for any purpose; and Fig. 8 is a section on the line 8-8 of Fig. 2.

Two side bars are shown at 8, 9. The bar 8 is provided with two slots 10, 11. Two guide ins are shown at 12, 13 and extend throng different portions of the bar 9, to which they are rigidly secured. The guide pin l2 is provided with an enlar ed portion let and with a fiat head 15, the en arged ortion 14 extending through the slot 10 o the bar 8. Another' guide pin 16 is carried by a thumb lever 14, and extends through the .slot'lL Another guide pin 18 is carrled by the bar 8 and is provided with an enlarged portion 19 and with a flat head 20, the portion 19 extending through a slot 21 in the bar 9. The slot 11 of the side bar 8 has the form indicated in Fig. -that is to say, it is substantiali)7 L-shapcd. The parts are so arranged that with the thumb lever 14a occupying the position indicated in full lines in Fig. 2, the side bars 8, 9 are in registry at the left of Fig. 1. It the lever 14 be swung outwardly a little, the side bars are not moved relatively to each other until the lever moves out far enough to allow a linger to be inserted beneath it. By this time it'begine to cause each of the bars'8, 9 to move relatively to the other. The' lever being' moved into the position indicated by dotted lines in Fi 2, the bars 8, 9 are considerably out of registry'at their ends to the left, ac-

cording'toy Figs. 2 and 5.

The side bars 8, 9, are provided with portions 22, 28, which at Ytheir upper edges are bent outwardly, or spaced apart, as indicated in Fig. 1. Because of their form, the portions 22,'23 (with the wedge-shaped space vbetween them) are virtually thicker than the end portions of the bars.

The slot 10 extends into the outwardly-bent portion 22, and the slot 21 extends into the outwardlybent portion 23. The upper edges at the ends of the portions 22, 23, are adapted to meet together, but thelower edges do not meet together. The side bars are also provided' with extending lips 24, 25. Whenever the bar 8 is moved to the left and the bar,9 is moved to the right, according to Fig. 2, the bars 8, 9 are forced bodily tcg Llama-1.a

gether in consequence of the action of the guide pins 12, 18, in the slots 10, 21, and the loxver edges are moved toward each other and the lips 24, 25, are either pressed tightly together or pressed against opposite faces of a blade inserted between them, as hereinafter described. The lip 25 has its ends bent slightly as indicated at 26, and the lip 24 has its ends similarly bent at 27. The parts are so arranged that when the lips 24, 25, are moved relatively to teach other in the general direction of their length, so as to be displaced relatively to each other as indicated in Fig. 5, and at the same time the bars 8, 9, are loosened relatively to each other by action of the guide pins 12 and 18 in the slots 10 and 21, the bent portion 26 of the lip 25 rides upon the adjacent iiat portion of the lip 24, and similarly the bent portion 27 of this lip rides upon the adjacent ilat portion ofthe lip 25. The lips 24,' 25 are thus forced apart as may be understood from Fig. 5. When, however, the side bars are moved into the position indicated in Figs. 1 and 4, and as indicated by' full lines in Fig. 2, the bent portions 26 engage the bent portions 27 and the lips 24, 25 are now pressed tightly together by action ofthe pins 12 and 18, as above described. Y

A razor blade is shown at 28. Inv order to insert it in the holder, the latter is brought into the position indicated in Fig. 5, the lips 24, 25, however, being in their lowermost positions, as indicated by dotted lines in Fig. 2. A gage box- 29 is next placed upon a table or the like, and the device is placed upon it, as indicated in Fig. 2 so that the lips 24, 25 extend nearly but not quite into engagement with the surface upon which the gage box rests. ,The blade 28 is next dropped in between the portions 22, 23, as

may be understood from Fig. 3. Next the lever 14a is moved into the position indicated by full lines in Figs. 1 and 2. This causes the lips 24, 25 to press against opposite sides of the blade and securely grip the same. The holder` may now be raised out of engagement with the gage box 29 and is ready for use.

In order to hone or strap the blade, the holder carrying the blade is wielded in much the same manner as an old fashioned razor.v

The proportions of the bars, and particularlyV of the portions 23, 24, is such that the blade necessarily assumes the proper angle combinationof a pair of side 4bars movable relatively to each other in the general di.- rection of their'common length, each of said bars being provided with a lip having a bent Aportion at its end and a flat portion mergmovements of the bars for clamping the bars together.

2. A safety razor blade holder comprising a pair of side bars each provided with a portion extending laterally therefrom and formedinto a lip, said lip having end portions bent in different directions to space said lips :slightly apart when said side bars are shifted endwise relatively to each other, lever mechanism connected with said side bars for shifting one of said side bars end-- wise in `relation to the other, in order to grip a razor blade between said lips, and meansfor clamping said side bars together.

3. ln a safety razon blade holder, the combination of a pair of side bars provided with laterally bent portions and further provided with straight portions and with slots located partly within said straight portions and partly within said laterally bent portions, guide pins extending through said slots and provided with heads, so that when one of said side bars is moved relatively to the other said guide pins tend to squeeze said side bars together, and a razor blade to be gripped between said outwardly extending portions when said side bars are thus squeezed together.

4. 1n a safety razor blade holder, the combination of a pair of side bars provided with end .portions disposed parallel with each other'and further provided with portions bent outwardly and thus spaced apart, said side bars being also provided with lips for holding a razor blade, means controllable by the travel of one of said side bars relatively to the other in the general direction of the length of said side bars for forcing connected With said side bars for moving one of said side bars in the direction of its length relatively to the other, and a gage box for engaging said side bars, said gage box having a depth greater than the Width of said lips in order to facilitate the posihoning of a blade in relation to said lips.

In testimony whereof I have signed my name to this specification in the presence of two subseribixnq Witnesses.
